City Gridlock

Turn traffic chaos into a city that flows.
City Gridlock is a traffic simulation puzzle game where every sign and signal matters. Study the routes, spot the bottlenecks, and decide how to keep the city moving. Place road signs, program traffic lights, and divert cars around busy intersections.
Press GO and watch your plan come to life. Cars head toward their destinations, buses stop to collect passengers, and queues begin to form. Keep drivers moving before their patience runs out, then adjust your strategy to improve traffic efficiency.
